WIRE-FEEDING MECHANISM FOR MACHINES FOR MANUFACTURING CHAIN-MAIL FABRIC.

Specification of Zetters Patent.

Patented Mar. 21, 1916.

Application filed June 3, 1915. Serial No. 31,859.

To all whom it may concern:

Be it known that I, NAPOLEON CI-IARGUE- RAUD, a citizen of the Republic of France,residing in Paris, France, have invented certain new and useful Improvements in VVire- Feeding Mechanism for Machines for Manufacturing Chain-Mail Fabric, of which the following is a specification.

This invention has for its object a distributing or feeding device applicable to machines which serve for .the'manufacture of metallic fabrics of the coat-of-mail type making use of metals of several colors; and the device isdestined to distribute successively and in the required manner, the metallic wires of difierent colors which may enter into the composition of the metallic fabric,

thus forming patterns which are obtained by the fact that in each row of rings forming the fabric a certain number of rings are made of a metallic wire, for instance, of white color (silver, German silver or nickel), a further number of rings being then made of a different metallic wire, for instance red wire (gold plated wire or copper wire). The combination and operation of this particular distributing device for the manufacture of patterned fabrics of the coat-ofmail type from wires of two or more colors of different natures, will be well understood from the following description having reference to the annexed drawings.

Figure 1 is a front view of the distributing device. Fig. 2 is a plan, one of the feeding tongs being shown in section. Fig. 3 is a view seen from the left-hand side of Fig. 1. Fig. 4 is a view seen from the right-hand side of Fig. 1. Fig. 5 is a rearview of the distributing device. Fig. 6 is a transverse section on line M M of Fig. 5. Fig. 7 is a fragmentary transverse section showing in detail one of the movable tongs; Fig. 8 is a. iorizontal section of the part 8 in Fig. 7 Fig. 9 is a fragmentary vertical longitudinal section through the stationary tongs, in the plane NN Fig. 10, of one of the wires;

Fig. 10 is a fragmentarv horizontal section,

on the line P-P in Fig. 9, beingin the horizontal plane of the wires; Fig. 11 is a sectional side view of one of the levers of the stationary tongs; Fig. 12 is an elevation of a cam wheel.

In order to enable the description of this distributing device to be easily followed and 1ts operation to be easily understood, it will be assumedthat the distributing device is to supply alternately at intervals well determined in advance and regulatable, a white metallic wire (as silver or nickel) and a red metallic wire (as gilded copper). The white wire is indicated in front on the plan, Fig. 2,and is designated by the numeral 13 while the red wire is indicated behind and designated by 13 The parts which relate to the two metallic wires will be indicated in this description by the same reference numerals; and those. which relate to the white wire have no index while those which refer to the red wire will have the index 1.

The distributing device forming the subject of the invention comprises stationary retaining tongs seen at the left-hand side in Figs. 1 and 2; and two (or more) movable tongs. In the example shown, only two movable tongs are shown as it has been assumed that the distributing device is constructed for two metallic wires. These movable tongs produce the successive feed of the one or the other of the two metallic wires which are to serve-for the formation of the coat-of-mail fabric. r r

The two tongs are independent, and they do not have exactly the same stroke, although the rings made from the two metals should be, and in reality are, identical; this is due to the fact that certain metals are more compressed than others by the action of the tools of the machine which form the ring pieces. The length of the hard metal which is necessary for making one ring piece may be for instance 8 millimeters while the length of wire of the other metal may be 9 millimeters.

Each of the two movable tongs comprises a part 1 (or 1 carried by a slide piece 2 (or 2 these slides move in guide ways 3 of dove-tail section, arranged upon the rear surface of the frame of the apparatus. Each of the parts 1 (or 1) possesses two cheeks 4, 4 (or 4: 4 between which may move a to'possess a pressure surface 7 Fig. 7 shows 7 .14, 14 Outside the cheeks 4, -1

lever 5 (or 5 pivotedat and so formed as separately one of the levers 5, with the pin 8 upon which it rests; this pin 8 is shown in plan in Fig. 8. Relatively to the operative portion 7 of the lever 5., the portion 1 of the tongs carries a pin 8 which is cut out over half of its upper surface so that only half of the upper surface which is indicated by 9 may exert a pressure upon one of the two metallic wires which pass with the tongs 1 below the lever 5. The lever 5 isfpressed from above by a spring 10 (or 10 which is interposed between said lever and a cross member 11 connecting the two cheeks 4:, 4;. Upon the end of the lever 5 is mounted a movable roller 12 the function of which will be presently explained.

The two metallic wires which serve for the formation of the fabric and which are indicated by dotted lines 13, 13 in Fig.2, are guided through the feeding tongs by tubes Between the cheeks of-the same pair of tongs, the

wires 13, 13 pass above the pin 8 as half of,

the upper surface of said pin is cut out in themanner explained above and shown in Fig. 8, only one of the two wires will be clamped between the pin 8 and the lever 5 of one pair of tongs. In the example shown in the drawings the white wire 13 is clamped and fed by the tongs shown on the right hand side of Figs. 1 and 2, or the left-hand side of Fig. The other tongs situated to the left, the pin of which is shifted by half a revolution with regard to that of the tongs shown on the right-hand side of Fig. 1, is

destined to feed the other metallic wire, that is the red wire 13 It will now be explalned 1n what manner the two pairs of feeding tongs are moved at the same time in the direction of the arrowv which moreover is regulatable and is" re-' 7 quired for the reason previously explained,

the tubes 14, 1 1 which guide themetallic wires in the tongs are not made of a'single piece for the whole length of the distributing device, but are made of sections, an interval beingprovided between the tongs. For the same reason the tongs 1, 1 are carried by two separate carriages 2, 2

The actuating mechanism of the tongs is operated by the lever 16, the lower end of which is provided with a roller 17 which is engaged by a cam, not shown in the draw- I ings.

frame 22 of the apparatus. carries at its upper end a pin 23 which takes 111 60 an elongated hole or a hole of a larger The axle 18 of said lever carries (see particularly Figs. 5 and 6) an arm 19 upon which acts a spring 20 fixed at 21 to the Said arm 19 diameter 241 formed in a part 25 integral with the slide 2 of the tongs 1 and said pin 23 also takes into a similar hole formed in the slide 2 of the other tongs 1 Owing to this arrangement the slides 2, 2 which carry the feeding tongs forthe two metallic wires 13, 13 and which are returned by the spr ngs 27 27 respectively, shown in Fig. 5, may perform travels of different length according to the nature of the metallic wires which the'tongs 1, 1 are intended to feed. 'The 28, 28 must be'fixed in a very exact manner. To this end the heads 29, 29 of these screws are provided on their peripheries with di-' visions, indices 30, 30 serving as marks 'for indicatingth'evalue of the return movement which may be performed byone or the other pair of feeding tongsl, 1, for supplying the suitable lengths of metallic wirecorresponding to either of the two tongs and required for forming one ring of the fabric.

The retaining tongs which are shown on the left-hand of Fig. 1 and onthe righthand side of Fig. 5, are shown separately in Fig.

1 to form the blankfor a ring of the coat of mail fabric, the position of these stop'screws' 9 which is a longitudinal section on N N of Fig. 10;.Fig. 10 being a horizontal sectionon line PP of Fig. 9. -These retaining" tongs comprise a box 3 fixed tothe frame of the apparatus and provided withthree' cheeks 32,32 and 33, betweenwhich move presser levers 3 1, 341 which coiiperate with stops 35, 35 constitutedby screws which pass through screw-threaded. holes of a cross-member 36. The levers '31, 341 one of which isseparately shownin Fig. 11, make pressure contacts under the infiuenceof lifting springs 10, 4 -0 with upper stops 35, 3 5 7 by means of the top ends ofscrews37, 37 which may be adjusted as regards position;

they are fixed in thedesired position by i means of set-screws 38, 38 while the counter-screws 35 are fixed in position by means of nuts 39, 39 i It will be noticed of the retaining tongs have a'movement in the opposite sense to that of the levers 5 of the feeding tongs 1, 1 ,the levers 3i exerting pressure when lifted, while the levers 5 exert pressure on descending. i

The feeding tongs l of the white wire13 1 which possess the pressure lever 5, and the that the levers 34., 3 1

lever 84 of the retaining tongs are operated at the same time by a common horizontal cross member 41, while the feeding tongs l of the red wire 13? which are furnished with the pressure lever 5 and the lever 34 of the retaining tongs are operated at the same time by another common cross member 41 The two cross members 41, 41 are arranged one behind the other; and upon these cross members rest the rollers 12, 12 arranged upon the extreme ends of the levers 5, 5 of the feeding tongs. The member 41 is integral with a rod 42 which is guided in ways 43; this rod is lifted at its lower extremity by a cam not shown in the drawings. Upon the transverse member 41 acts a spiral spring 44 which returns the said transverse member in the downward direction. The transverse member 41 is also integral with a rod 42 arranged close to the rod 42 and lifted by the same cam as the latter rod, a spring 44 having always the tendency to move the transverse member 44 downwardly. Either the one or the other of the two transverse members 41, 41 but only one at a'time, may rest in its upper position upon a stop which at the required moment moves from below one of the transverse members to below the other; this stop is constituted (see Fig. 1) by a finger 45 which is pivoted at 46 and is integral with an arm 47,. the end of which bears against a cam 48. This cam is indicated by dotted lines in Fig. 1 and is also shown separately in view and in the same position in Fig. 12. In Fig. 1 of the drawings the end of the arm 47 is shown resting.

upon one of the projecting parts of the cam 48; the arm 45 is then displaced toward the left, its extreme end is therefore underneath the transverse member 41 which actuates, for the purpose of elevating the pressure levers, on the one hand the feeding tongs 1 of the red wire 13 and on the other hand the lever 34 of the retaining tongs. As soon as the extreme end of the arm 47 enters a recess of the cam 48, the arresting finger 45 is displaced from a position below the transverse member 41 to a position below the transverse member 41 the transverse member 41 will then remain in its upper position acting in the manner described upon the lever 5 of the feeding tongs of the white metallic wire 13 and the lever 34 of the retaining tongs.

The cam 48. the function of which has just been described. is integral with a ratchet wheel 49 upon which acts a pawl 50 pivotedto the upper end of the lever 16; each time when the lever 16 is operated by its'cam, the

pawl 50 pushes the ratchet wheel 49 by one tooth, and the cam 48 advances at the same time. So long as the arm 47 of the stop 45 rests upon the same portion, proiection or recess, of the cam 48, (in Fig. 1 it is shown .the ratchet wheel 49;

resting upon a projection), the stop 45 continues to maintain the transverse member 41 in its upper position; but when the end of the arm 47 moves into a recess of the arm 48, the finger 45 is returned by its spring 51 and takes its position below the transverse member 41 so that the latter descends under the action of its spring 44. When the finger 45 has thus been moved toward the right, Fig. 1, its extreme end acting as a stop is below the transverse member 41 which has been raised by the cam which acts at the same time upon the two rods 7 The function of the retaining tongs is the following: lVhen the feeding tongs recede in the direction opposite to that of the arrow 15, 1 and 5, in order to take up wire, the two levers 34, 34 of the retaining tongs are raised and both bear upon the metallic which pass through the tongs, the one owing to the fact that the corresponding transverse member 41 is maintained in its raised position by the finger stop 45, the other owing to the fact thatthe corresponding transverse member has been raised by the projection of the cam which operates the two transverse members 41, 41 During this action of the lifting cam, the two metallic wires are therefore clamped by the levers of the retaining tongs and the feeding tongs move backward to take up wire. Only that wire will be fed by its tongs, the lever of which has not been raised by its transverse member 41.

Between the ratchet wheel 49 and the cam 48 is arranged a disk 52 the circumference of which is formed with teeth the number of which is thesame as that of the teeth of into one of these teeth of the disk 52 takes a small roller 53 (Fig. 1) mounted upon the extremeend of an arm 54 which is raised by a small spiral spring the pivoted arm 54 performs the function of a locking pawl. The disk 52 is provided upon its face, Fig. 1, with numbered divisions corresponding to the teeth. These divisions have different colors, for instance white and red, and are numbored in the example shown 1, 2, 8, 4, 5, upon a segment of white color, 1, 2, 3, upon a following segment of red color, and so on. The colored and numbered divisions guide the workman in his work which in the example shown is supposed to consist in the production of a fabric having five successive links of white metallic wire, then three links of red wire, then five links of white wire, etc. The circular developments of these various successive sectors correspond to the circular developments of the projections and recesses of the cam 48 which operate the retaining arm 45 which maintains, in its raised posltion, the one or the other of the transverse members 41, 41 in the manner-above explained. I

The actuating lever 16 carries at its upper end a small elbow-lever 56 pivoted at 57, one arm of which carries a knob 58,

longer upon the ratchet wheel. In this manher only one wire may be fed, either the one or the other of the two, according to the position of the arm i7, which takes into a recess or bears upon a projection of the cam 48.

An index (52 fixed to the frame of the aparatus indicates exactly the divisions of the disk 52.

.T he knurled edged knob (51 whichis integral with the ratchet wheel 49, the cam 48 and the'toethed and numbered disk 52, enables the various members to be set in position manually when the formation of a rowrof links has commenced; the workman knowing that for example two links of red wire are to be formed first, turns the milled edged knob in such-a manner that the index 62 is placed opposite one of the members 2 of a red colored portion of the disk 62;

the red wire will then be firstifed at the be ginnlng of the formation of a row so as to supply two successive links of red wire.

' The description deals by way of example with an apparatus which enables two different metallic wires to be fed; a distributing device of this kind could be also constru ted so as to distribute three or more wires; it would then obviously be necessary to provide as many feeding tongs as metallic wires and to multiply the pressure levers of the retaining tongs and also suitably increase the number of parts which actuate the feeding tongs and the levers of the retaining tongs.

A- distributing device of this kind may obviously be used for any machine for manufacturing coat-of-mail fabrics, and particularly for the machine which forms the subject of applicants patent application dated 23 January, 1915,.N0. 3,966. It would also bepossible to arrange a distributingdevice on each side of the parts of the machine which serve for making the fabric, and this would enable the coatofmail fabrics to be made of a good many different metallic wires, and would enable the number of patterns to be increased.
